Preheat your waffle iron. Set a baking sheet in the oven and preheat to 200 degrees F. Make the brown butter (see here for a brown butter tutorial)

In a small bowl, combine the flour, sugar, baking powder, baking soda, sea salt, and spices. In a large bowl, whisk the eggs and then add the buttermilk and pureed squash. Stir until smooth. Fold in the dry ingredients and then drizzle in the butter. Grease waffle iron according to manufacturer’s instructions. Add 1/3 cup batter per waffle. Set cooked waffles in the oven. Serve with butter, syrup, and sliced fruit.
